API 609 WAFER BUTTERFLY VALVE

Lug Butterfly Valve Rubber Lined Product Information

Lug butterfly valve rubber lined is available to do the repair in the downstream pipelines and equipment directly, which is mounted between two matching flanges of the piping with bolts & nuts. According to actual piping conditions, lug type butterfly valve can be manufactured according to different flanges standards, such as ASMEB16.1, EN1092, AS2129, DIN2501, BS4504, JIS10K, GB 17241.6. Lugged type butterfly valve can be mounted onto the piping ends as exhaust valve too. We can manufacture the lugged butterfly valve in accordance with the standards of EN593, API609 and ASME B16.34 with the sizes of 2″~24″ (DN50~600mm).
